If you’re a little fuzzy about where 24 left off when the series ended in 2010, don’t worry—the cast and producers are too.

“We have to check Wikipedia,” executive producer Manny Coto joked during the Television Critics Press Tour in Pasadena.

Four years after the series ended, 24 will return with a two-hour premiere on May 5. Kiefer Sutherlandwill reprise his iconic role as the indestructible Jack Bauer and Mary Lynn Rajskub will return as his tech-savvy sidekick Chloe O’Brian in 24: Live Another Day.

“The audience that we’ve had that has stayed with us over the years has been so spectacular and supportive and loyal; to not give them the best that we have to offer would be very disappointing,” Sutherland told critics. “I’m about as anxious and wound up as I’ve been in a long time.”

While the show will still cover another very bad day in Jack’s life, there will only be 12 episodes in this new season. Each episode will cover one hour but may skip one or two hours between episodes.

The series begins filming in London in a few weeks and the entire season will take place across the pond. “We really liked the idea of placing it somewhere where it would automatically be different and automatically put Jack in a different cultural and social context,” Coto said.

The show will pick up four years later with Jack still a fugitive and still hunted. William Devane returns as the now President James Heller and Kim Raver is back as Jack’s erstwhile love interest Audrey Raines. Yvonne Strahovski (Chuck, Dexter) joins the cast as a CIA agent who has been on the hunt for Jack Bauer.

Rajskub joked that she thought Chloe would return as director of the Counter Terrorism Unit (CTU). “I thought it would be, ‘Chloe for President,’ she said. “But where they started her is just somewhere really cool.”

Chloe has been damaged in the intervening four years and is not the same person she once was. She no longer works for CTU and has turned against the government. “For lack of a better term, she’s more radical. A [Edward] Snowden type character,”Coto said.
Jack and Chloe begin the season pitted against each other. “That’s a dynamic that Mary Lynn and I get to play that’s very exciting,” Sutherland said.

Since the series ended, there has been talk of a feature film. Sutherland said the script for the film is very different from this new season of 24 and there remains an opportunity to do the film. “But right now we’re very passionately focused on these 12 episodes,” Sutherland said.

In addition to Strahovski, this new season of 24 will feature Giles Matthey, Gbenga Akinnagbe, Michael Wincott and Judy Davis.
